  The SAP error message SCA_DS303 indicates that there was a failure in retrieving system information for a Remote Function Call (RFC) destination. This error can occur in various scenarios, particularly when dealing with system connections in SAP systems, such as during data transfer or system monitoring tasks.
  Causes:
  
  
  Incorrect RFC Destination Configuration: The RFC destination may not be configured correctly in the SAP system. This could include incorrect connection parameters, such as the target system's hostname, system number, or client number.
  
  
  Network Issues: There may be network connectivity issues between the SAP system and the target system. This could be due to firewall settings, network outages, or incorrect routing.
  
  
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations to access the target system.
  
  
  Target System Unavailability: The target system may be down or not reachable, which would prevent the retrieval of system information.
  
  
  SAP Gateway Issues: Problems with the SAP Gateway service on either the source or target system can lead to this error.

  Check RFC Destination Configuration:
